Cell type-specific processing of non-motor signals in the external pallidum

The external globus pallidus (GPe) regulates motor control. However, whether the GPe encodes non-motor information remains unclear. Two recent studies, by Johansson and Ketzef, and Katabi et al., pro-vide in vivo evidence for GPe neuron processing of sensory stimulation and reward cues via a division of labor among its cell types.

Automated summary

Two recent studies provide in vivo evidence that the external globus pallidus (GPe) not only regulates motor control but also encodes non-motor information through cell-type division of labor, processing sensory stimulation and reward cues.
